SEEQLFIOA'EION formingpart of Letters Patent No. 677,647, dated July 2,1901. Application filed February 25, 1901. Serial No. 48,775. (Nomodel.)

To all whom, it may concern:

Be it known that I, HENRY ELLIOT, a citizen of the United States,residing in the city of St; Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Railway-Frogs, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My present invention relates to a sliding railway-frog, the object beingto produce a frog of this character which will not be liable to get oforder, as the parts are held in proper relation to each other.

The invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a top or plan view of my improved frog. Fig. II is anenlarged vertical transverse section taken on line II II, Fig. I. Fig.III is a like view taken on line III III, Fig. I. Fig. IV is ahorizontal section taken on line IV IV, Fig. VI. Fig. V is a Verticalsection taken on line V V, Fig. I. Fig. VI is a like view taken on lineVI VI, Fig. IV.

Referring to the drawings, 1 represents the point-rails, 2 theheel-rails, and 3 the shifting rails. The rails 1 and 2 are firmlybolted to a bed-plate 4, while the rails 3 rest upon the bed-plate andmay be shifted thereon in a direction transversely of their lengths.Between the rails 3 is a distance-block 5, through which pass bolts 6,that also pass through they webs of the rails, the rails being thusfirmly clamped together forward of the pointrails 1. Back of the pointof the rails 1 is a bridge-bar 7, that passes beneath the rails 1 andthe ends of which are connected to the webs of the rails 3 by bolts 8.The bar 7 fits up against the base of the rails 1, as seen in Fig. II,so that the bar and the rails 1 act to hold the rails 3 down upon theplate 4. The forward ends of the rails 3 are provided with fingers 9,adapted to slide through loops 10, secured to the plate 4, these fingersand loops also acting to hold the rails 3 down against the plate 4,While not interfering with the lateral movement of the rails. The endsof the rails 2 and 3 meet, as shown in Fig. I, and they are beveled off,so as to come up snugly together when the rails 3 are shifted to bringeither one of them into alinement with the corresponding rails 2. Boltedfirmly to the webs of the rails 3 are bars 11, the ends 12 of whichoverlap onto the Webs of the rails 2. The inner faces of the-ends 12 ofthe bars are beveled oif, as shown at 13, Fig. IV, and these ends of thebars are loosely connected to the Webs of the rails 2 by means of bolts14. Sleeves l5 fit between the bolts and the bars 11, so that the nutson the bolts can be tightened up against a firm rest without the barsbeing clamped immovably to the webs of the rails.

16 represents blocks bolted or riveted to the webs of the rails 2 andwhich fit in notches 17 in the inner faces of the bars 12, these barsacting to prevent endwise movement of the bars 12 and rails 2 withrelation to each other.

It will thus be seen that the rails 3 can be shifted laterally on thebed-plate 4 to bring either one of them in line with the correspondingrail 2, while the rails 1 and 2 are firmly held to the bed-plate and therails 3 are securely held from vertical movement with relation to thebed-plate, the whole forming a substantial sliding frog that is notliable to get out of order.

The holes in the bars 12 in which the sleeves 15 fit should be madesufficiently long to allow for the fleeting or endwise movement of thebars asthe shifting rails are moved.

I claim as my invention 1. Ina railway-frog, the combination of abed-plate, point and heel rails rigidly secured to the bed-plate, andshifting rails rigidly connected together and movably held to thebed-plate and which have a loosely-hinged connection with the heel-railswhereby the shifting rails can fieet as they are moved, substantially asset forth.

2. In a railway-frog, the combination of a bed-plate, point and heelrails rigidly secured to the plate, shifting rails rigidly connectedtogether and loosely resting on said. plate, and bars secured to theshifting rails and loosely hinged to the heel-rails whereby the shiftingrails can fleet as they are moved, substantially as set forth. v

3. In a railway-frog, the combination of a bed-plate, point and heelrails firmly secured to the bed-plate, shifting rails rigidly con=neeted together and movably resting on the bed-plate, and abar securedto each shifting rail, said bars being hinged to the heel-rails beyondthe ends of the shifting rails, substantially as set forth.

4. In a, railway-frog, the combination of a bed-plate, point and heelrails rigidly secured to the bed-plate, shifting rails movably securedto the bed-plate, a bridge-bar secured to the shifting rails and whichpasses beneath the point-rails, and bars rigidly secured to the shiftingrails and which are connected to the heel-rails by bolts passing throughsleeves
